unity 5.5.0p1@@@@undefined reference to `UnityAdsEngineSetReadyCallback'

LM-Zhang · December 13, 2016, 6:39pm

I got the error below on Unity5.5.0p1.

but everything is ok on Unity 5.4
how can i fix it?

JoshPeterson · December 14, 2016, 12:48pm

This is an existing bug in Unity 5.5.0f3 and 5.5.0p1 which prevents the Unity Engine ads integration from working with Android and IL2CPP. You can correct this bug switching to the Asset Store Ads package for now. We’re planning to have a fix for this issue available soon.

sevensails · January 7, 2017, 4:42am

I have a similar error on XCode output window after build and run on device (and the game crashes or freeze)

Unable to resolve pinvoke method 'UnityEngine.Advertisements.iOS.Platform:UnityAdsEngineSetReadyCallback (UnityEngine.Advertisements.iOS.Platform/unityAdsReady)' Re-run with MONO_LOG_LEVEL=debug for more information.

Also, I’m running 5.5.0p3 and not using IL2CPP. Is this related?

JoshPeterson · January 9, 2017, 12:58pm

It does seem to be related. So are you running on iOS with Mono? Does it work with IL2CPP instead?

sevensails · January 9, 2017, 10:49pm

It worked with IL2CPP

Kebenchen · January 10, 2017, 2:16am

I also have this error in our game, although the game doesn’t crash but ads do not work. This was reported on the Game performance page on unity analytics

EntryPointNotFoundException: Unable to find an entry point named 'UnityAdsEngineSetReadyCallback' in '__InternalDynamic'.

The weird about this is that when we installed from XCode the Unity Ads work. But it is the same build we submitted, the one from the store doesn’t work.

JoshPeterson · January 10, 2017, 12:54pm

Ok, thanks for the information both. So it looks like the Unity Ads engine integration does not work with Mono on iOS. That is a bug, but I’m not sure whether we will correct it, as you can’t ship to the Apple App Store using Mono anyway. But it might be worth submitting a bug report and we can investigate it.

As a work around, I believe the asset store Unity Ads package does work with Mono on iOS, so you may be able to try that instead.

Am I correct in thinking that this is only an issue with Mono on iOS? Or is there another platform/scripting backend configuration that is a problem?

Kebenchen · January 12, 2017, 6:33am

I believe that it doesn’t work on IL2CPP for iOS as well (compiled with IL2CPP backend and tested on iPhone 5S - ads works when running from XCode but doesn’t work when downloaded from TestFlight to test).

Confirming as well that the Unity Ads from the asset store works. We just submitted an update for our game.

will try to do additional tests this weekend

JoshPeterson · January 12, 2017, 12:43pm

@Kebenchen

This issue should be corrected for iOS and IL2CPP on 5.5.0p3 and later. Can you give that version a try?

Kebenchen · January 13, 2017, 7:44am

I can confirm that it is working on iOS IL2CPP built with 5.5.0p3 but with the Asset Store version not the one in the Unity Services Panel.

JoshPeterson · January 13, 2017, 12:43pm

@Kebenchen

Thanks for the information. Can you submit a bug report with your project? There might be something subtle going on here that we have missed.

michael-v · February 9, 2017, 5:53pm

5.5.1p3 android version - started to behave the same. 5.5.1p1 works.

Strom_CL · February 21, 2017, 2:49am

5.5.1p4 also fails to build using IL2CPP on Android using the builtin Ads services, referencing UnityAd stuff.

JoshPeterson · February 21, 2017, 12:59pm

@Strom_CL

Unfortunately this bug slipped back in to a patch release. It will be corrected in the 5.5.2 release though.
